Description

Supply Air 12x9x2 White Corrugated Shipping Boxes are single-wall corrugated cardboard boxes constructed from kraft paper with a white exterior finish. Each box measures 12 inches in length, 9 inches in width, and 2 inches in height (interior dimensions). The boxes feature a 32 ECT (Edge Crush Test) rating, indicating the stacking strength of the corrugated board. The construction consists of a single layer of fluted corrugated medium sandwiched between two linerboard sheets. Each box is supplied flat (knocked down) and assembles into a Regular Slant Container (RSC) configuration by folding along scored lines. The top and bottom flaps interlock to form the closure without requiring tape or adhesive for light-duty applications, though tape is recommended for heavier contents or extended transit. The white exterior surface is uncoated kraft paper suitable for labels, stamps, or direct printing. Available in multiple pack quantities to accommodate varying volume needs. Manufactured in the United States. Pack quantities include 25, 50, 100, and 200 boxes per order.
